Experimental activities and test facilities
The SSL has designed and mounted the test facility with unique characteristics. The test facility is placed in Obninsk State Technical University of Nuclear Power Engineering (OGTU AE) and is intended to carry out the thermo-hydraulic experiments at the hydrodynamic model (HDM) of the tank reactor.

The unique characteristic of the test facility is the possibility of precise measurements of flow rate in any assembly imitating the fuel rod assemblies of full-scale reactor. Experimentally obtained map of flow rate is used to ground the design solutions and operation modes of the tank reactor operation.

The experimental section with the full-scale model of the reactor fuel rod assembly has been created to ground design of the channel-imitator. Obtained experimental data with numerous experiments at other stands let to ground HDM construction.
Realized system of thermal hydraulic parameters measurements includes both industry means of the flow rates and pressure drops measurements and the laboratory measurement system operating simultaneously. This system allows to ground at the test facility the accepted engineering solutions, also the test facility may be used for education purposes.
